Align object's orientation -rotation, transform, and scale to another object's orientation
Yeah that exists in Blender 2.8 as well as in 2.7.

Just select the object or objects you want to apply the rotation to first (press shift to select multiple objects). 
Then also select the object you want to copy the rotation from at the very last. 
Then open the Properties Region (menue on the right side , shortcut [n]).
There you hover over the rotation or location or scale and click the right mouse button. Then you select 'copy all to selected'. You can also only copy the one value you hover over by selecting 'copy single to selected'.
